Power Supply Unit Wiring
Be sure to wire power lines, control lines, PC cables, and DC I/O cables sepa-
rately. Supply power separately when using a second power supply in a duplex
system. Use an output terminal (built into Power Supply Unit) for an external
relay to form an emergency stop circuit that will turn OFF the system when the
PC operation stops, to prevent a malfunction in the PC from affecting the whole
system.
The Backplanes of CVM1D CPU Racks, Expansion CPU Racks, and Expansion
I/O Racks can be used in a duplex system, and 5-VDC power can be supplied
simultaneously to the Units mounted to these Racks from two Power Supply
Units. If one of the Power Supply Units malfunctions in a duplex system, power
will automatically be supplied to the Units mounted on the Rack from the other
Power Supply Unit.
Wire the two Power Supply Units separately, so that the system can continue to
operate if there is a power failure in one of the Power Supply Units.
